Mathematics is a game if you practise it a lot. As you practise your ability to calculate grow and after that you can makes tricks similar to what we get from Vedic Maths tricks.
For example it will give same result if a number is divided / multiplied by 4 once and the same number is divided multiplied twice by 2. But when we do it with 2 calculation becomes easy. So in case of 4 do it twice by 2.
Multiplication: 32 x 4 can be done as 32 x 2 x 2 = 64 x 2 = 128
Division 32 / 4 can also be solved as 32 / 2 / 2 = 16 / 2 = 8
